The study focused on analyzing the levels of air quality parameters across 2 areas of Dehradun – Clock Tower & Nehru Colony, both pre and post Diwali 2021.

The data analyzed showed higher concentrations across all parameters during the 5-day period around Diwali. While the concentrations of SO_x & NO_x were within National Ambient Air Quality Standards of the Central Pollution Control Board, PM₁₀ & PM_2.5 concentrations exceeded the standards. It was also noted that the levels almost reached back to pre-Diwali levels within a week post-Diwali.

These could impact both plants and animals with devastating effects, causing severe respiratory problems.
